Jonathan Finamore
I had Bio-One do a massive cleanup after a water issue in my home. They did a masterful job. Cleaned and sanitized desired areas and got rid of years’ worth of clutter. Roger, Marco, Monica and Uduak (the company’s owner) were all very professional and helpful. They were EXPENSIVE! but flexible and thoroughly committed to client satisfaction. I would not hesitate to hire Bio-One again for similar jobs if needed in the future.

    Uduak Ogunsiakan
    Owner
    I am a Registered Nurse, specializing in homecare. Alongside my team of nurse assistants, we visit the homes of elderly individuals to offer services including bathing, feeding, light housekeeping, and any necessary support to enable them to remain in their own homes rather than transitioning to a facility. In our work, we frequently encounter seniors facing challenges like hoarding, mold, or cat odor issues. Securing a reliable company to address these matters proved to be a significant challenge. However, upon discovering Bio-One, I am confident that we now have a valuable resource to assist those in need.

    Bio One saved me and my mother’s lives, we both struggle with mental health and our hoarding situation had reached its breaking point, but when we enlisted the help of Bio One we felt we were in good hands. Uduak is so kind and non judgmental it felt like she truly cared about our health and safety, like we were inviting a family member into our home to help with our troubles. We be forever in your debt Bio One. Thank you!

    I cannot say enough about the incredible team at Bio-One. After experiencing a deeply traumatic event in my home, I was overwhelmed and unsure where to start. From the very first interaction with Uduak, her compassion, professionalism, and understanding stood out. Uduak and her team handled the situation with such care, treating my home—and my family—with the utmost respect. The cleaning was meticulous and thorough, restoring my home to a place where I could feel safe and comfortable again. Uduak and her team went above and beyond, not only addressing the physical aspects of the cleanup but also showing empathy that made all the difference during such a difficult time. I am forever grateful for Uduak and her team outstanding service and would recommend Bio-One to anyone in need of compassionate and high-quality cleanup. They truly are a blessing in the toughest of times.
